# UOS Genesis SHA-256 Digest

> UOS Genesis SHA-256 Digest is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Computes a SHA-256 cryptographic hash digest for a given input payload

## Facts

- Endpoint: POST https://genesis.palsus2023.workers.dev/v1/sha256_digest
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/uos-genesis-sha-256-digest-999e5117
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_u3QtwsmtW7FAY9VPj1su2

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability uos-genesis-sha-256-digest-999e5117 -d '<json body>'
```

Example prompt: Can you compute the SHA-256 hash of this string: 'Hello, World! This is my data payload'?

## When to prefer this

Use this endpoint when you need a simple, serverless SHA-256 hash computation without spinning up local code or a heavier cryptography library — especially useful in AI agent pipelines that need deterministic content fingerprinting, deduplication keys, or integrity checksums on the fly. It's a pay-per-call micro-utility, ideal for occasional hashing tasks in automated workflows.

## Known failure modes

- Empty or missing input body returns an error
- Oversized payload may be rejected depending on worker limits
- Network timeout on Cloudflare Workers edge
- Payment failure (x402) if USDC balance is insufficient — request blocked before processing

## How this service works

UOS Genesis machine utility: sha256_digest

## Output

Returns a SHA-256 hex digest string representing the cryptographic hash of the submitted input payload. The output is a deterministic 64-character hexadecimal string.
